Best of Soul is a best-of compilation featuring the greatest hits from Korean R&B/pop singer BoA's Japanese releases between the years 2001 and 2004.
Comprised of the usual blend of ballads and more dance-oriented pop tunes, Best of Soul also features a contribution from Japanese hip-hop group Soul'd Out.
The songs "Quincy", "Kono Yo no Shirushi," and "Meri Kuri" were recorded especially for the album, with the former two appearing as a double A-Side, and the latter as a Christmas single.
